Hoover Dam is really two guitar sounds bolted together, and the joy of it is the size of the step between them. Getting it right is less about either tone than about making sure the clean one is loud and present enough that the chorus lands as a lift rather than just as noise.
What makes the tone. Clean, slightly compressed chime in the verses with a hint of chorus, then a full bright distortion for the choruses. Both share the same top-end voicing, which is what makes the transition sound like one guitar getting bigger rather than two different players.
The analogue recipe. One amp, set clean but loud, with a drive pedal for the choruses rather than a channel switch - it keeps the EQ consistent. Add a light compressor always-on for the verse chime. Set the pedal's level so the jump is in size and thickness, not just volume.
On a Boss GT-100 / GT-1000 / GX-100. Two patches or two channels off the same clean amp model: verse with compressor and a touch of chorus, chorus with an overdrive block in front. Keep the amp, cab and EQ identical between the two so only the drive changes.
On a Kemper. One clean profile plus a distortion stomp for the choruses, rather than two separate profiles. Use the performance mode so the reverb tail carries across the switch - the join is where this song lives.
Straight to the settings. The Soulster Tonebook for fans of Sugar → has the chords, capo positions, tempos and dialled-in settings for this one.
On paper, too. The "Hoover Dam" Northern Life print → is the same song, printed. Also on the Practice print → and the Studio print →.
